The Costa Smeralda

Outside Mainland China, some cruise ships were quarantined after passengers developed symptoms or tested positive for 2019-nCoV. The Costa Smeralda was quarantined on 30 January off Civitavecchia in Italy, after passengers developed flu-like symptoms – the quarantine was lifted when tests for the virus came back negative. Two further ships were quarantined on 5 February: Diamond Princess in the Port of Yokohama, Japan and World Dream, which returned to Hong Kong after being refused entry to Kaohsiung, Taiwan. In both cases, passengers and crew tested positive and the ships remained quarantined as of 6 February.
